PHOTORECEPTOR DRUM AND IMAGE FORMING APPARATUS INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a photoreceptor drum in which an air stream can be efficiently made to flow into the photoreceptor drum for cooling the photoreceptor drum, and an image forming apparatus including the photoreceptor drum.SOLUTION: A photoreceptor drum 121 includes a drum sleeve 121A and a drum flange 121C. The drum flange 121C includes a flange part 121C1, a bearing 121C2 and a connected rib 122. The flange part 121C1 is fitted to the drum sleeve 121A. The bearing 121C2 is disposed inside the flange part 121C1 in an axial direction and pivotally supports a shaft to rotate the photoreceptor drum 121. An opening Z is formed by using a clearance in the axial direction between the flange part 121C1 and the bearing 121C2. An air stream is efficiently made to flow into the inside of the photoreceptor drum 121 through the opening Z.
